Tax Preparation & IRS Representation
Get practical help with individual tax returns, business taxes, and past-due returns. Work with an Enrolled Agent who reviews your situation and explains your options. Ongoing advice follows engagement terms; quarterly planning meetings are available for a separate fee.
Dedicated Practice

Enrolled Agent Representation
Licensed to represent taxpayers before the IRS
Comprehensive tax preparation for individuals and business owners. We take time to understand your situation and claim every deduction and credit you are legally entitled to.
Not sure if your past returns were calculated accurately? We review federal and state returns to uncover missed deductions, incorrect depreciation, or audit risk factors.
Behind on filing? We pull IRS transcripts, reconstruct missing financial records, prepare prior-year returns, and assist with penalty abatement and IRS payment plans.
Received a letter or proposed assessment from the IRS or FTB? We review the notice, explain it in plain language, and prepare formal responses backed by Enrolled Agent representation.
How Tax Filing Works
Work with a tax preparer remotely or by appointment. Begin with a consultation about your situation, scope, and pricing, then sign an engagement agreement before sharing tax documents.
After engagement, we will provide access to our secure client portal for uploading tax documents. Office visits are by appointment. We accept tax-document drop-offs after a signed engagement agreement and by prior arrangement.
Complete a brief tax interview. Your tax preparer reviews deductions and multistate issues. We will provide a timing estimate after reviewing your completed documents and the scope of your return. Timing varies with complexity and deadlines.
We generally review your draft tax return with you before filing. If you prefer to review it on your own or cannot meet, we can provide a draft copy and answer your questions. After you approve the return and e-sign the required filing authorization, we file it.

Client Reviews
We strive to provide the highest quality services to all our valued clients. Here are some of the reviews from our satisfied customers.
I had no idea I could contribute to an IRA even though I was over the income limit. Milan explained what a backdoor Roth IRA is and how to contribute to it.
My wife and I own a couple rental properties, we never depreciated any of the homes and didn't know we were supposed to. Our tax accountant figured out our missed depreciation and fixed our taxes.
Working with Mraz Tax Solutions has been a great experience. They prepared my business tax return, helped me setup a payment plan with the IRS and calculated quarterly payments so I don't owe in the future.
I uploaded my documents to my tax preparer Milan. He prepared my taxes and when they were done, we reviewed them over video. It was easy and I didn't have to go anywhere or print anything.
